Cast iron classification under sales tax turns on commercial identity: rough castings may qualify, finished articles do not.

For sales tax purposes, the expression "cast iron" was construed to include rough castings in their crude or unfinished form, because the entry covers the primary saleable form of the commodity rather than only raw metal. Finished articles made from cast iron, such as pipes, manhole covers, fittings and machinery parts, were treated as commercially distinct commodities once further processing changed their identity and marketability. Tax already suffered on the raw material did not exempt such finished products; separate tax liability arose where a new commercial commodity came into existence.

Issues: (i) Whether cast iron castings, particularly rough castings made from tax-suffered pig iron or iron scrap, fall within the expression "cast iron" in item 2(i) of the Third Schedule to the Andhra Pradesh General Sales Tax Act, 1957. (ii) Whether finished articles made out of cast iron, such as pipes, manhole covers, fittings and machinery parts, continue to be the same declared goods or become distinct commercial commodities liable to tax.

Issue (i): Whether cast iron castings, particularly rough castings made from tax-suffered pig iron or iron scrap, fall within the expression "cast iron" in item 2(i) of the Third Schedule to the Andhra Pradesh General Sales Tax Act, 1957.

Analysis: The expression "cast iron" in section 14(iv)(i) of the Central Sales Tax Act, 1956, and the corresponding State entry was construed in the context of the statutory scheme, the Government of India's clarificatory letters, and G.O. Ms. No. 383 issued under section 42(2) of the State Act. The clarifications were treated as relevant aids to interpretation, but only to the extent that they explained the scope of the entry. On that basis, rough castings in their crude or unfinished form were regarded as falling within "cast iron", because the expression refers to the primary saleable form of the commodity and not merely to the raw substance.

Conclusion: Rough cast iron castings are covered by "cast iron" and are taxable as declared goods only if they remain in that rough or unfinished form.

Issue (ii): Whether finished articles made out of cast iron, such as pipes, manhole covers, fittings and machinery parts, continue to be the same declared goods or become distinct commercial commodities liable to tax.

Analysis: The legal test applied was whether the goods retained their identity as the declared commodity or, by further processing and finishing, emerged as separate marketable commodities. Finished products ready for use were treated as commercially distinct from cast iron, even if manufactured from cast iron or pig iron that had already suffered tax. The controlling principle was that when a new commercial commodity comes into existence, it becomes separately taxable; mere use of tax-suffered raw material does not confer immunity. The Tribunal had erred in proceeding on the assumption that all disputed goods were merely cast iron castings without examining their nature, stage of processing, or commercial identity.

Conclusion: Finished cast iron products are not covered by the entry as cast iron and remain liable to tax as distinct commercial commodities.

Final Conclusion: The matters required fresh examination of the true nature and character of the goods; the Tribunal's orders could not stand and the cases were sent back for reconsideration in accordance with the legal position stated above.

Ratio Decidendi: For sales tax purposes, declared goods are taxable by their retained commercial identity; rough castings may fall within "cast iron", but finished articles or further processed products made from cast iron are separate commercial commodities and cannot claim exemption merely because the raw material had already suffered tax.
